River Valley will participate in the third annual "Stick it to Cancer" campaign, in which high school field hockey teams across the country donate proceeds from their matches to the National Foundation for Cancer Research.
The Yuba City school is donating proceeds from its JV and varsity games on Monday against Bella Vista to the organization.
"After participating in this event last year and raising nearly $900, we are excited to be involved again this year," said River Valley coach Sarah Lopes in a press release. "This cause is close to my heart, as my mom died from breast cancer in 1993, when I was 6.
"Breast cancer awareness and research has always been something that I involve myself in, and this event is a great way for our girls to raise money for such an important cause and learn how important early detection, screening and awareness is for women."
To raise funds, the teams will be donating all gate proceeds, accepting general donations, holding a bake sale and selling T-shirts.
Both the JV and varsity teams will be wearing pink "Stick it to Cancer" jerseys in support of the cause.
The JV game begins at 5:30 p.m., with the varsity match to follow at 7 p.m.
